Extracranial Extension of Intracranial Atypical Meningioma En Plaque with Osteoblastic Change of the Skull

Meningioma is a common primary tumor of central nervous system. However, extracranial extension of the intracranial meningioma is unusual, and mostly accompanied the osteolytic change of the skull. We herein describe an atypical meningioma having extracranial extension with hyperostotic change of the skull. The patient was a 72-year-old woman who presented a large mass in the right frontal scalp and left hemiparesis. Brain magnetic resonance imaging and computed tomography scans revealed an intracranial mass, diffuse meningeal thickening, hyperostotic change of the skull with focal extension into the right frontal scalp. She underwent total removal of extracranial tumor, bifrontal craniectomy, and partial removal of intracranial tumor followed by cranioplasty. Tumor pathology was confirmed as atypical meningioma, and she received adjuvant radiotherapy. In this report, we present and discuss a meningioma en plaque of atypical histopathology having an extracranial extension with diffuse intracranial growth and hyperostotic change of the skull.

Intracranial Lipoma in Medulla Oblongata

Intracranial lipomas are rare, and most of these tumors are found in the region of the corpus callosum, followed by cerebellopontine angle. We present a case of a intracranial lipoma in 30-year-old man. Brain computed tomography (CT) scan and magnetic resonance images (MRI) showed a mass in the medulla oblongata extending to foramen magnum. The histopathologically, diagnosis of lipoma was confirmed. Although there were several cases of cervical intraspinal lipoma extending into posterior cranial fossa, there have been no previous reports of a lipoma arising from the medulla oblongata that extended into the foramen magnum. We describe a rare case of intradural subpial lipoma in the medulla oblongata with a review of the literature.

Intracranial Germ Cell Tumour with extra cranial extension in a four month old infant – a case report.

Germ cell tumours of the central nervous system infiltrating the ipsilateral extracranial tissues are not a common presentation. A case of intracranial germ cell tumour with extracranial extension in a four month old infant is reported. The patient had undergone excision of the extracranial lesion followed by combination chemotherapy. Twelve months after the completion of the treatment the patient is doing fine and is on regular follow up.

Extracranial Extension of A Pterional Meningioma: Case Report

The authors report a case of pterional meningioma invading the sphenoid bone, orbital roof and lateral orbit, and temporal bone with hyperostosis, which extended into temporal muscle. Extensive removal of orbital, sphenoid and basal skull bone was carried out with total excision of tumor mass in and out of the cranium. Preoperative exophthalmos still remained postoperatively. The mode of extension, result of surgery and CT findings are discussed.
